Implement local transcript aggregate verification

[piotr-roslaniec]

• Related issue: Ferveo WASM bindings (including browser client transcript verification) taco-web#192
• Blocked by Fix a validator ordering issue with PVSS & DKG instances #95
• Some of the TODOs will be fixed in a subsequent PR (i.e. WASM bindings)
• Things to look out for doing the review:
  • Refactor of DKG and PVSS code to expose verification logic
  • Breaking changes in the serialization of crypto primitives (using compressed representation everywhere)
  • Changes in ferveo-py API (renamings, removal of some of the unused primitives, new primitives)

@KPrasch @derekpierre
I'm adding you as reviewers to let you know about some of the breaking changes in the Python bindings. I'm going to walk you through the updating process once I release a new ferveo-py version.

Please feel free to review this PR at your convenience.
